WILLIAM IV. NORRIS, OF BALTIMORE, MARYLAND; MARY R. NORRIS ADMINISTRATRIX OF SAID W. W. NORRIS, DECEASED.

BOTTLE=STOPPER.

SPECIFICATION forming part of Letters Patent No. 259,418, dated June 13, 1882.

Application filed April 7, 1880. (No model.)

To all whom it may concern:

Be it known that I, W'ILLIAM W. NORRIS, of Baltimore, State of Maryland, haveinvented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

My invention relates to that class of stoppers for bottles in which a rubber ball is used and attached to a bottle in such a manner that it can be swung over and away from the top of the bottle, according as it is desired to close and open the same, thus taking advantage of the elasticity and adaptability of the ball to adjust itself to the mouth of the bottle.

Elastic halls have been connected and secured to bottles in various ways; but none of them with which I am acquainted have been supported on their sides to prevent their form becoming flattened laterally or expanded horizontally under the heavy pressure to which they are subjected by the traction of the yoke or fastening. Balls as ordinarily used for stoppers have been simply perforated diametrically and the wire forming the bail or yoke passed through the perforation. Balls have also been molded with an internal metal ring, and the latter provided with trunnions to engage with the bail. Stoppers thus constructed are rather difficult to mold, and do not give to the ball the required support to produce a stopper having lasting qualities.

The object of my invention is to produce an elastic ball'stopper with acentral metallic and tubular support of larger diameter than the yoke-wire, to prevent indentation and cutting of said ball by the yoke under pressure, and to sustain the sides of the ball at both ends of the internal tubular support to prevent its lateral expansion.

My invention consists in the combination of a rubber ball, an internal tubularsupport, and the yoke of a bottle; and also, with the above combination, of broad collars secured at each end of the tubular support, as will be hereinafter described, and pointed outin the claims.

In the drawings, Figure 1 represents a perspective view of my improvement, and Fig. 2 a vertical central section of the same.

In the drawings, A represents the neck of a bottle; B, the-wire-yoke retainer, connected in the ordinary manner to the neck of the bottle by means of the wire 0, which takes two or three turns around the hooked ends of the yoke and forms hearings in which said hooked ends can turn.

1) represents the rubber ball. It is provided with a central metal tube, 01, thus placed, either while the ball is molded or after it has been molded, in a diametrical perforation of the latter. This tube d is of sufficient diameter to permit the yoke to pass loosely through it and present a broader surface against indentation and cutting than can be obtained wit-h the yoke itself.

To both ends of the tube cl collars e, of coinparatively large size, are secured by slightly flanging, flaring out, or riveting the ends of said tube.

If the ball is molded around the central tube, the securing of the collars to each end thereof can also be done very conveniently before the molding. These collars give to the ball the necessary support against lateral expansion, and render the stopper as effective after having been retained in position upon the mouth of the bottle for a length of time as when first applied.

After having the hall constructed as above described, the wire forming the yoke is passed through its tubular support and bent as shown, with hooked ends, and said yoke and stopper are ready to be secured to the bottle with the small wire O.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a rubber ball, an internal tubular sleeve, 01, and the yoke of a bottle-stopper passing through said sleeve, substantially as and for the purpose described.

2. The combination of a yielding elastic ball, an internal tubular sleeve, d, collars 0 upon the ends of said sleeve, and the yoke of a bottle-stopper passing through said sleeve and collars. substantially as described.

WILLIAM WYATT NORRIS.
